Athan's mother, Tatyana, asked the court to make the defendant's sister to testify under a lie detector.

"She might have known of her brother's plan, but is denying it," she claimed.

The court told her that a lie detector test is not used in the UAE.

Meanwhile, the suspect's defence lawyer, Hassan Al Riyami, requested a psychiatric committee to test the mental stability of his client and suggested the man has mental health problems.

"There is no way that a stable, sane person would commit such a crime," he told the court.

The suspect allegedly lured the boy to the rooftop, sexually assaulted him then choked him to death with a piece of laundry line.

The child was found dead the next day by maintenance workers.

Mr Al Riyami also asked the court to allow him to sit alone with his client with the presence of a translator, because the defendant cannot speak English or Arabic. The court told him this was his right and he did not need approval.

"The case file is huge and it requires some time to prepare my case," he added.

The court told the parents that it would be at least 45 days before the psychiatric report is ready and the case continues.
